Download and play for free. Let's get started.

Make sure Steam is installed and configured.

Install the Steam Client onto your computer, and create an account if you don't already have one.

Step2

Open Steam, and install Source SDK Base 2007.

Within the Steam client, select the "Library" tab. Then, click on the drop-down menu that says "All Games", and select "Tools." You'll find Source SDK Base 2007 in the list below. Double-click it to install. Or, if you're lazy, just click here.

Step3

Download CSPromod and run the installer.

Download CSPromod BETA 1.10 from one of our trusted mirrors. If you want to play the game, just download the installer .exe file, run it, and follow the on-screen prompts to install CSP. If you want to host a server, download the server .zip file instead.
